AUTOMATIC meme-imcamsa FOR CARDlNG-MACHINES.

SPECIFICATION forming part of LettersPatent No. 592,135, dated. October 19, 1897.

' Application filed June 25,1897. Serial No. 642,222. on model.)

To aZZ whom it may camera.-

Be it known that I, HENRY FIELDFJK, of

Olneyville, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Automatic Feeding Mechanism for Oardin'g-Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to the accompanying drawings, "and to the letters of reference marked thereon, which form a part of this specifica- Lion.

This invention relates to that part of a carding-machine that automatically regulates the amount of woolor other fiberfed to the carding-cylinders. f i

- It is fully explained'and illustrated in this specification and the accompanying drawings.

Figure 1 is a perspective view of the cardfeeder. Fig. 2 is a separateview of the stopgears, enlarged. Fig. 3 is an edge view of the same gears seen in Fig. 2. Fig. & is a separate view of the gear-tripping plate.

In carding wool or other fiber itis necessary, to make batting of uniform weight and thickness, to Weigh or otherwise deliver a certain amount of the fiberto a given length of the apron that conducts it to the feed-rolls;

and the. object of this invention is to provide surface of the belt,to catch the fiber and carry a simpler and more complete stop-motion put' in operation by the weighing device used to divide the fiber into proper or equal quantities. The following is a description of its construction and operation: I

Dis a'receptacle or case into which the wool or fiber is put in bulk to be carried to the feed-rolls of the card by means of a ver-' tically-traveling belt A and the horizontal apron B. The belt A, which is studded with hooked teeth, or teeth set at an angle to the it over toward the apron, is held on a roll b at the top of the case and a roll I) on the stud of the gear-wheel d at the bottom, which drives the belt. A gear-wheel g, held on a stud above the gear (1, with which it engages, has a chain-Wheel 'i on one side that carries the chain c, that drives the doifer G in the upper part of the case by means of a similar chain-wheel 6, fast on the doffer-shaft, and an arm 8 on the same shaft vibrates the beater N by the rod f, which connects the arm 5 with a like arm on the beater. The heater N, by its vibratory motion at a proper distance from the belt, removes the surplus fiber carried up by the teeth, and the doffer G, by a circular motion, causes the fiber carried over by the belt to leave it and fall into the chamber H."

F is a gear-wheel on the end of a shaft that receives a continuous motion from the card.

A shaft '1", that receives a continuous mo- ,tion from the feed-rolls ct by means of a chain belt Z2, has a revolvingcross-armj on its outer end. A curved plate J, which forms the bottom of the chamber I-I,is hung on a I'OClU,WhlGh rod has a cross-arm 0, fast on its outer end, and one part of this cross-arm has an adjustable Weight 25 on it to overbalance the plate J when it has no fiber on it, and this weight t is so adjusted as to allow the plate J to tip down when the right amount of fiber has collected on it.

'A' dog-T, held on a stud just below the weight 2., has a curved arm extending up from it with a hook m on the end that catches a pin 10' in the outer end of the weight-arm o, and holds it from rising, while the lower end of the dog T. rests on the raised portion of the cam 'a on the inner side of the cross-arm j on shaft 0", and when the cam turns, so that the dog drops into one of the hollows in the cam, the hook 071. will release the pin it, and at the same time one of the arms j will strike the arm 1; on the rod 'v and tip the plate J down to the dotted line a, so all the fiber on it will be discharged onto the feed-apron B, to be conveyed to the feed-rolls a.

At the same time that the cross-arm 0 is released from the hook m, the other end of the arm will allow the rod 0' to drop and operate the stop motion below. This stop mechanism consists of a cross-bar L, hung near its middle on the stud that holds the gear 01, which bar L has an intermediate gearwheel G, held on a stud fast in the bar, so as to engage with the gear 0?! and drive it when the gear G is held up in engagement with the gear F, which, as before stated, receives a continuous motion from the card. An adjustable Weight P is held on the outer end of the bar L to balance the gear G. A circular plate 71 (see Fig. 4) is held free to turn on the back of the gear F, and a projection s on one side of it projects far enough beyond the teeth of the gear that when the plate is turned with the projection toward the gear G the projection will come in contact with a row of studs y on the back of gear G (see Fig. 2) and will push the gear out of engagement with the driving-gear F. The rod 0 passes through a hole in the tab g on the side of the plate 11, and also through a hole in the end of the bar L, and a long open spiral spring h is put 011 the upper part of the rod 0 to press on the tab 9, and a short similar spring d is put between the regulating-nut r, on the lower end of the rod 0, and the end of the bar L. hen a proper quantity of fiber has collected in the chamber II on the plate J, it will overbalance the weight if and drop until the pin k catches in the hook m, as shown in Fig. 1. Then when the shaft r turns, the dog T will drop into one of the hollows in the cam a and turn the hook back from the pin 7s, and at the same time one of the arms j will strike the arm 0 and cause the plate J to tip clear down and deposit the fiber on the apron B, and the rod 0 drops so that the spring h will turn the plate at and bring the projection s in between the gears G and F, pushing the former down out of engagement with the latter, and stop all motion of the gears G, d, and g, and, consequently, of the belt A, doffer G, and the beater N, until the fiber has left the plate J. This plate will then be raised again to place by the weights t and I, and the rod 0, in rising, will turn the plate 11/, by means of a collar fast on the rod, allowing the gear G to be raised by the weights P and t,

to again engage with the driving-gear F, giving motion to all the parts stopped, so that the process of collecting the fiber in chamber II will go on as before until another portion is collected, when the same operation of the stop-motion will take place.

Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent The combination with a case to hold the fiber, of an elevator-belt, a beater to brush off the surplus fiber, a doff'er to detach the fiber from the belt into a chamber having a movable bottom said bottom provided with a shaft, a lower gear to drive the belt, a stud on which lower gear is mounted, a bar also held on said stud, a second stud in one end of said bar, an intermediate gear on said second stud, a weight on the other end of said bar, a driving-gear, an arm on the shaft of said movable bottom, a rod connected to said bottom adapted with said bar to draw the intermediate gear into engagement with said driving-gear, a circular plate held free on said driving-gear and provided with a projection to separate said gears, a side tab on said circular plate with a hole in it to receive said rod and a spring on said rod to press on the top of said tab, a collar on said rod to raise said tab, a connection of said rod with said bar, substantially as described.

In testimony whereof I have hereunto set my hand this .Ztth day of June, A. D. 1897.
